纽约州北部的黑帽山雀(Parus Atricapillus)在10月份出现了囤积食物的强度高峰。我们在一年中的六个不同时间捕获了山雀，并测量了几个大脑结构的体积。我们发现，与缓存食物的空间记忆有关的海马体结构在10月份比一年中的任何时候都有更大的体积，相对于大脑的其他部分。我们的结论是，食物囤积的强度与海马结构的体积之间存在关联，并暗示解剖结构的增强可能是由于空间记忆的增加所致。
Black-capped chickadees (Parus atricapillus) in upstate New York show a peak in food-hoarding intensity in October. We caught chickadees at six different times of the year and measured the volume of several brain structures. We found that the hippocampal formation, which is involved in spatial memory for cached food items, has a larger volume, relative to the rest of the brain, in October than at any other time of the year. We conclude that there is an association between the intensity of food hoarding and the volume of the hippocampal formation and suggest that the enhanced anatomy might be caused by the increased use of spatial memory.
